Definitions

  • the present application relates generally to a method and apparatus for receiving reference signals in support of flexible radio communication in a communication network, and more particularly, to managing a multilevel approach for receiving reference signals, such as for cell detection, in support of an initial unconnected or an already connected state relative to the network.
  • UE user equipment
  • wireless communication devices communicate with other communication devices using wireless signals, such as within a network environment that can include one or more cells within which various communication connections with the network and other devices operating within the network can be supported.
  • Network environments often involve one or more sets of standards, which each define various aspects of any communication connection being made when using the corresponding standard within the network environment.
  • LTE Long Term Evolution
  • UMTS Universal Mobile Telecommunications Service
  • GSM Global System for Mobile Communication
  • EDGE Enhanced Data GSM Environment
  • synchronization signals are transmitted within the center 6 physical resource blocks (PRBs) of a transmission channel bandwidth, where a PRB consists of 12 subcarriers. While this can make it easier to locate and identify the synchronization signals, restricting the location of the synchronization signals in a predetermined way with this level of specificity can make the system less flexible in terms of introducing a new type of service, which might otherwise beneficially employ different forms, such as forms that can incorporate different numerology sets. Strict adherence to a specific detailed and predefined signaling structure can make a system less flexible in terms of avoiding strong interference to a primary synchronization signal and/or a secondary synchronization signal. Furthermore, this can make a system less flexible in terms of enabling shared spectrum access with other radio access technologies.
  • PRBs physical resource blocks
  • the present inventors have recognized that a multilevel approach for receiving reference signals can be used to allow a more flexible approach for cell detection as part of initiating a communication connection and/or maintaining an ongoing communication connection with a network. Such a flexible multilevel approach can further be used to support dynamic coexistence between multiple types of communications in accordance with both new and legacy communication standards for a more progressive migration to newer communication standards.
  • EP 2,882,213 A1 describes a measurement configuration which contains a reception control signal which contains the radio resources, the signal sequences, the carrier frequencies, and the bandwidths of discovery signals, and other pieces of information related to the discovery signals.
  • Embodiments provide a method and apparatus for receiving reference signals in support of flexible radio communication including cell detection within a flexible radio communication system.
  • FIG. 1 is an example block diagram of a system 100 according to a possible embodiment.
  • the system 100 can include a wireless communication device 110, such as User Equipment (UE), a base station 120, such as an enhanced NodeB (eNB) or next generation NodeB (gNB), and a network 130.
  • the wireless communication device 110 can be a wireless terminal, a portable wireless communication device, a smartphone, a cellular telephone, a flip phone, a personal digital assistant, a personal computer, a selective call receiver, a tablet computer, a laptop computer, or any other device that is capable of sending and receiving communication signals on a wireless network.
  • the network 130 can include any type of network that is capable of sending and receiving wireless communication signals.
  • the network 130 can include a wireless communication network, a cellular telephone network, a Time Division Multiple Access (TDMA)-based network, a Code Division Multiple Access (CDMA)-based network, an Orthogonal Frequency Division Multiple Access (OFDMA)-based network, a Long Term Evolution (LTE) network, a 5 th generation (5G) network, a 3rd Generation Partnership Project (3GPP)-based network, a satellite communications network, a high altitude platform network, the Internet, and/or other communications networks.

  • 5G 5 th generation
  • 3GPP 3rd Generation Partnership Project
  • FIG. 2 is an overview of multiple communication regions 202 in an exemplary cellular communication system 200.
  • each of the multiple communication regions is often associated with a particular base station 204.
  • more than one base station can support a particular communication area, such as in edge areas where regions may overlap.
  • a particular base station can support one or more communication regions.
  • each particular base station 204 can support at least three regions 202, where the base station is positioned at a shared vertex of each of the three regions.
  • the regions 202 can be further subdivided into multiple still smaller regions, using one or more narrow beams 206.
  • An example of the further subdivision of at least one of the regions 202 is shown.
  • Another example highlights the possibility that a more focused beam could be directed to coincide with the location of a user equipment 208.
  • the user equipment 208 could similarly communicate with the base station 204 via a similarly more focused beam with same or different beamwidth.
  • the base station and the user equipment can employ antenna arrays, having multiple radiating and reception elements, that together can be employed to create various transmission and reception profiles or beamforming patterns.
  • the corresponding size and shape of the different regions can often have an impact on the ability of the network to reuse frequencies while supporting communication connections between the various wireless communication devices located throughout the coverage area.
  • the present inventors have recognized that in supporting cell detection in a new radio access technology, that any dynamic coexistence between the new radio access technology and any preexisting should be taken into account in order to support a more progressive migration.
  • a numerology comprises one or more of an OFDM/SC-FDMA subcarrier spacing, a cyclic prefix length, number of symbols comprising a slot, time-frequency portion bandwidth etc.
  • Different numerology sets may differ in one or more of parameters or characteristics of a numerology.
  • the cell might be able to configure multiple time-frequency portions using different numerologies, it may be possible for synchronization signals transmitted with a baseline (or reference) numerology to be shared by all numerology configurations.
  • a baseline or reference numerology may be dependent on the carrier band such as reference numerology of 15kHz OFDM/SC-FDMA subcarrier spacing for low carrier frequency band (such as below 6GHz e.g., 2GHz) and reference numerology of 120kHz OFDM/SC-FDMA subcarrier spacing for high carrier frequency band (such as above 6GHz, e.g., 28GHz).
  • TRP dense transmission and reception point
  • PSS primary synchronization signal
  • SSS secondary synchronization signal
  • Two step measurement procedures are employed to provide necessary flexibility on system configuration (e.g. number of operating beams) and yet to keep cell detection complexity low: first, narrow band measurement without beam differentiation and physical broadcast channel (PBCH) decoding for candidate cells, and secondly, wideband beam measurement according to the indicated system configuration.
  • PBCH physical broadcast channel
  • PSS/SSS sub-band mobility measurement reference signals (MRS), and physical broadcast channel (PBCH) carrying a master information block (MIB) message are transmitted on the same sub-band, for example a subset of available subcarriers, and relative timing of MRS and PBCH with respect to PSS/SSS are preconfigured and known to both UE and transmission and reception point (TRP).
  • TRP transmission and reception point
  • UE can perform the following steps:
  • the measurement configuration may include frequency information when the synchronization signals are transmitted, such as the information element (IE) 'IndexForSynchSignalLocation', carrier frequency information, and bandwidth information, for example maximum allowed measurement bandwidth.
  • the wideband beam measurement configuration such as the information element (IE) 'maxNumberOfAntennaPorts' corresponding to the maximum number of antenna ports for the wideband MRS, can be signaled.
  • the UE can identify cell ID from PSS/SSS detection and frequency information of PSS/SSS indicated in the measurement configuration. Thus, the connected mode UE does not need to decode PBCH to obtain a full cell ID.
  • FIG. 5 illustrates an example allocation in an exemplary frame 500 across an available channel bandwidth of primary synchronization signal (PSS)/secondary synchronization signal (SSS), sub-band measurement reference signal (MRS), physical broadcast channel (PBCH) and wideband measurement reference signal (MRS) for at least three cells.
  • the gray areas 502 correspond to allocations associated with cell 1
  • the areas 504 highlighted by ascending diagonal lines correspond to allocations associated with cell 2
  • the areas 506 highlighted by cross hatching correspond to allocations associated with cell 3.
  • the more square shaped allocations 508 in each instance represents a proposed allocation for PSS/SSS, sub-band MRS, and PBCH.
  • the vertical rectangle shaped allocations 510 in each instance represents a proposed allocation for wideband MRS for each of the respective cells.
  • Each interval identified by the symbol, T S represents a single subframe duration.
